Title: Toner cartridge with hopper exit agitator
Inventor: MEECE KERMIT ARNOLD
IPC: G03G15/08
Filed: 1997-12-19
Granted: 2000-09-26
Abstract: A toner cartridge (1) has a cylindrical toner hopper (61) with a rear wall (61a) defining an output opening well above the lower part of the hopper.  A paddle (63) is rotated in the hopper.  The exit surface (61aaa) declines downward to form a chamber for the toner adder roller (45) and developer roller (43).  This configuration discourages toner from returning to the hopper after it has been electrically charged.  To improve movement of toner past the opening an agitator bar (65) extends across the cartridge near the exit surface.  The bar is pivoted at both ends and has a portion (65a) which extends into the path of the paddle.  As the paddle rotates, it moves the agitator upward until the curved paths of the two members reach separation, at which time the bar drops by gravity.  The bar jars toner loose and eliminates jams of toner.  The flat surface of the bar, when it has been moved up,  partially blocks the exit opening, which desirably limits toner flow.

Title: Refrigeration system
Inventor: BARROWS RICHARD C
IPC: F25B49/02
Filed: 1997-11-12
Granted: 2004-05-25
Abstract: A refrigeration system (10) which controls subcooling by controlling the amount of refrigerant diverted from the condenser (14) to the receiver (16) based upon the difference in temperature between the phase change transition temperature of the refrigerant in the condenser (14) and the liquid refrigerant temperature at the condenser output.  Refrigerant is bled from the receiver (16) to charge the system until the condenser pressure causes the difference between the phase change and liquid temperatures to exceed a predetermined value. A controller (100) responds to this condition by simultaneously operating a bleed valve (32) at the receiver inlet (34) and a release valve (56) at its outlet to draw refrigerant from the condenser (14) into the receiver (16). As the condenser pressure drops, the difference between the phase change and liquid temperatures decreases toward the desired amount, and the cycle begins again.

Abstract: An optical amplifier for use with a solid state laser which includes a pair of elongated slabs of a solid state lacing material, such as a rare earth doped yttrium-aluminum-garnet (YAG) crystal. Two embodiments of the invention are disclosed. In both embodiments of the invention, each of the elongated slabs is formed with a square or generally rectangular cross-section. The slabs are configured such that the longitudinal axes of the slabs are generally co-axial aligned and the slabs are orientated such that the major axis of the slabs are generally orthogonal. By configuring the two slabs to be orthogonal with respect to one another, the integrated thermal lens becomes azimuthally symmetric and can be compensated by a simple external lens. In addition, the negative lensing affect along the major axis of one slab is used to compensate for the positive lensing affect along the minor axis of the other slab and vice versa, thus minimizing the affects of the astigmatism. In an alternate embodiment of the invention, a dove prism is used to rotate the beam instead of rotation of the slabs.

Abstract: A sublimating card printing apparatus can be minimized with a simple construction and can provide multiple functions. A sublimating card printing apparatus for recording predetermined information in a magnetic recording medium and/or semiconductor memory provided on a card material and moreover, for printing an image based on a supplied printing signal on a card material, comprises a rotary transporting means for switching a transporting direction of the card material rotatably provided on the last of a linear transport path on the card material, a card tray for containing the card material through the rotary transporting means in the case where errors occur in recording in a recording/reproducing means of the magnetic recording medium or a recording/reproducing means of a memory recording medium, and a memory recording/reproducing means provided on the rotary transport path through the rotary transporting means. Therefore, the length of the transport path can be reduced and the card tray can be contained in the apparatus and thus, the whole apparatus can be minimized with multiple functions.

Abstract: An electronic projector has a projection system that includes a spatial light modulator (SLM) for imparting image information to the projected light beam. The light beam leaving the SLM is prepolarized in a defined orientation and the projected light is polarized in the same orientation so as to effectively block any light that has been scattered within the projector and become depolarized. The SLM may be a digital mirror device (DMD) or a liquid crystal device (LCD). Reflective surfaces within the projector may be covered or coated with material that polarizes the reflected light at an orientation orthogonal to the defined orientation.

Abstract: In a call center (100) of a business, if it is determined (314-318 or 320) during the handling of a call involving a party who is a customer of the business that the party is at risk of being lost as a customer to the business, an identifier of the party, such as ANI, is captured (300) and stored (322) along with an "at risk" indication. The determination may be made either automatically by detecting (314-318) that the party terminated the call while on hold, or manually (320) by the agent handling the call or a service observer whereupon the agent or observer pressed an "at risk" feature button (112) on their terminal (105, 110). On a subsequent call to or from that party, the stored identifiers (380) are searched (306), and when it is determined (308) that the party is identified therein as being at risk, the call is given (310) special treatment (400-426)~a higher-than-normal level of service~and is identified (428) to the call's handler .as involving an "at risk" customer, in an attempt to avoid loss of the party as a customer.

Title: Flexfoils having connector tabs
Inventor: HESSELBOM HJALMAR
IPC: G02B6/43
Filed: 1998-02-18
Granted: 2003-12-16
Abstract: In an optical flexfoil (1) comprising optical waveguides such as optical fibers (3) ends of the optical fibers can be located at inner and edge positions of the flexfoil. Cut-outs (7, 9) are formed around such fiber ends to form tabs (11, 13) which can be bent laterally from the plane of the flexfoil (1) so that the ends of the fibers (3) are located at the exterior edges of the tabs. This allows a connection of the optical fibers to external devices in different directions such as a connection in a direction perpendicular to the flexfoil (1). Thus, the flexfoil (1) can be used as an optical supplement to an electrical backplane (21), the tabs (11) extending through openings (29) in the backplane. Also, an easy handling of the flexfoil is achieved, since no connection tabs extending beyond the edges of the flexfoil are required. This is advantageous for example in polishing the ends of the fibers at the tab ends.
